I will not be going back here for BMW service, and you shouldn't either.

My experience:
-Tuesday, brought my wife's car in for our scheduled 10:15am appointment for a warranty repair
-Wednesday, told: "ordered part, ETA Thursday"
-Thursday, told: "part arrived, should be ready on Friday"
-Friday, told: "the wrong part came". Asked: how they didn't realize this on Thursday. Told: "we ordered the right part and the right part box came, wrong part in box" (seemed very hard to believe, but will become less believable soon). Told: "should be done tomorrow"
-Saturday, told: "the part did not arrive on the truck today, next day we are open is Tuesday". Asked: is the part going to arrive on Tuesday? Told: "we can only know on Tuesday when the part gets scanned in off the truck." Asked: Seems like you should know if the part is on the truck when it is scanned for departure. Told: "I wish we could" (this can't possibly be true)
-Tuesday afternoon, told: "The part is on backorder with no ETA, car is drivable, I will have the car ready for you to pick up later today" (how in the world did it take a week of me being without a car to find out the part is on backorder?). Told: "The car is ready for pickup". Drove in to pick up the car. Car brought out for my wife to drive home. When she gets in she sees exposed wiring and parts on the seat... the car was not put back together!?! We refuse to take the car (obviously) and are promised that the car will be put back together and delivered to our home on Wednesday.
-Wednesday afternoon at 4pm no car, no word from Schomp, reached out and told: "got it done, just wrapped up". Asked: "When will it be delivered?" Told: "Tomorrow AM"
-Thursday: Car finally arrives back at my house after 10 days without a car, two trips to the dealer, and countless time spent trying to get an ETA. Zero accountability.

This is the service experience for a luxury brand?
